Merrill–Crowe process Wikipedia

The solution is separated from the ore by methods such as filtration ( horizontal leaf type clarifiers) and counter current decantation (CCD). Afterwards a very clear solution is achieved by using precoated filters applying diatomaceous earth. Oxygen is then removed by passing the solution through a vacuum deaeration column.

Decantation Wikipedia

Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving the other component or the more dense liquid of the mixture behind.

What Is Decantation and How Does It Work? ThoughtCo

Decantation is a process to separate mixtures by removing a liquid layer that is free of a precipitate.. The purpose may be to obtain a decant (liquid free from particulates) or to recover the precipitate. Decantation relies on gravity to pull precipitate out of solution, so there is always some loss of product, either from precipitate not fully falling out of solution or from liquid remaining ...

Countercurrent multiplication Wikipedia

Countercurrent multiplication was originally studied as a mechanism whereby urine is concentrated in the nephron. Initially studied in the 1950s by Gottschalk and Mylle following Werner Kuhn's postulations, this mechanism gained popularity only after a series of complicated micropuncture experiments.. The proposed mechanism consists of pump, equilibration, and shift steps.

Counter Current Decantation Design Formula

The principle of Counter Current Decantation is simply that, when water or solution is to act upon solids, both are made to pass, in contact, in opposite directions, so that at each end the strongest or most potent portion of either is acting upon the weakest or most exhausted portion of the other. The recovery of dissolved gold and silver from slime pulp in the cyanide process, as first ...
